importorigin: Import data from Origin7 ITC data sheet

Description

The importorigin function imports integreted ITC data from csv files. The source csv files can be generated, for example, by exportation from spreadsheets generated after integration in Origin7 ITC module.

Usage

importorigin(x)

Value

A list with each column in the input file as one component. Elements in each component are converted to the numeric type. NAs are generated if non-numerical values are present. NAs at the end of each component are deleted. These components are in the list if imported from Origin7: DH,INJV,Xt,Mt,XMt,NDH,B

DH: heat exchange in mcals for each injection
INJV: injection volume in ul for each injection
Xt: ligand concentration in the ITC cell before each injection
Mt: protein concentration in the ITC cell before each injection
XMt: the molar ratio of ligand to protein in the ITC cell after each injection
NDH: heat exchange in cal/mole for each injection
B: heat exchange in cal/mole for each injection, fitting results from Origin7

Arguments

x: a character string of the name of the text file in csv format exported from Origin7 ITC data sheet

Examples

Run this code

if (FALSE) {
data(data_origin1);

## using the loaded data to generate an Origin7 data file as input
write.csv(data_origin1, "origin_data.csv", quote=FALSE, row.names=FALSE)

## import data
x1 <- importorigin("origin_data.csv");
}
